Convert into mixed number 81/3 and -29/2

LuckyWell [14K]

Hmmmm to convert from improper to mixed, simply do the division of both, the quotient gets upfront, the remainder as the numerator, for example,

how many times 3 goes into 81? well, 27 times, with a remainder of 0, thus $\bf 27\frac{0}{3}$

how many times does 2 go into 29? well 14 times, with a remainder of 1, thus $\bf -14\frac{1}{2}$

vodka [1.7K]

Answer:

32 people came in blue cars and 6 people came in red cars

Step-by-step explanation:

Technically, all 48 people came in red or blue cars, but I'm assuming that's not what the question is asking.

To find how many people came in blue cars, we do 2/3*48 which is equal to 32 people.

To find how many people came in red cars, we do 1/8*48 which is equal to 6 people.

Free_Kalibri [48]

Answer:

Johnny will be able to reach the safe zone before the gate is closed.

Step-by-step explanation:

Given that:

Distance of Little Johnny from safe zone = 4000 feet

Time = 3 minutes

Speed = 22 mph

To find:

Will Johnny be able to reach the safe zone ?

Solution:

Johnny can only be safe if he can travel 4000 feet in 3 minutes with the given speed.

Let us try to find out, the distance that he can travel in 3 minutes at speed of 22 mph.

Let us have a look at the formula of distance traveled:

$Distance = Speed \times Time$

Time = 3 minutes = $\frac{3}{60}$ hrs

Speed = 22 mph

$Distance = 22 \times \frac{3}{60}\\\Rightarrow Distance = \dfrac{22}{20}\ miles \\\Rightarrow Distance = 1.1\ miles$

We know that 1 mile = 5280 feet

Therefore 1.1 miles = 5280 $\times$ 1.1 feet = 5808 feet

Distance traveled by Little Johnny is greater than 4000 feet.

Therefore Johnny will be able to reach the safe zone before the gate is closed.
